Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples:
A kind of system controlling waste gas spreading, including waste gas header 1, waste gas recovery general pipeline 2, nitrogen seal device 3, multiple groove tanks 4.It is useless
Gas general pipeline 1 is connect with groove tank 4 by exhaust gas branch pipe 5, and waste gas header 1 is equipped with oxygen content analyzer 11 and the first fast cut valve
12, oxygen content analyzer 11 and the first fast cut valve 12 interlock.It is set between oxygen content analyzer 11 and the first fast cut valve 12
There is independent release region, independent region of diffusing is equipped with solenoid valve.When oxygen content analyzer 11 monitors on waste gas header 1
When oxygen content is more than threshold value, the first fast cut valve 12 is closed, the solenoid valve for opening independent release region starts waste gas spreading.
Waste gas recovery general pipeline 2 is connected with gas-pipe line total system, and waste gas recovery general pipeline 2 and groove tank 4 pass through waste gas recovery branch
Pipe 6 connects.Suction is power before the air blower being equipped with using gas-pipe line total system, by the useless of each device and multiple groove tanks 4
Gas is recycled to the burning of gas-pipe line total system, prevents exhaust gas uncontrollable discharge.
Nitrogen seal device 3 is equipped with for nitrogen valve 31, lets out nitrogen valve 32, nitrogen header pipe 33, nitrogen branch pipe 34.Nitrogen header pipe 33 passes through
It is connected for nitrogen valve 31 with storage nitrogen tank 7.When the air pressure in groove tank 4 is less than preset value, opening is for nitrogen valve 31, and nitrogen is by nitrogen header pipe
33, nitrogen branch pipe 34, which enters, keeps 4 environment micro-positive pressure of groove tank in groove tank 4.
Groove tank 4 is equipped with nitrogen interface 41, breather valve 42, deadweight safety valve 43, desorption tube 44.Nitrogen interface 41 passes through nitrogen
